1 N-12 WT ( watertight ) ib pipe . It's a revolution that began nearly 15 years ago when ADS pioneered the watertight joint for corrugated polyethylene pipe . The ADS N-12 WT ib pipe our third generation of watertight joint technology is yet another leap forward in watertight performance. The ADS N-12 WT ib pipe incorporates patented technology developed in the aerospace industry. A 2" wide proprietary ceramic/polymer composite is fused to the outside wall of the built-in bell, improving the joint's integrity and tolerance control. A patented gasket, that meets all requirements of ASTM. F477, increases its sealing forces as internal or external hydrostatic pressure increases. Flared bell and spigot significantly improve ease of installation. N-12 WT ib pipe is so advanced in its design that it is easy to put your confidence in for long-term reliability. BENEFITS: Variety of diameters and lengths fit any project APPLICATIONS: pipe requires no extra couplers, grout or other Storm Sewers Culverts & Cross Drains sealants for installation due to built-in bell Sanitary Sewers Slope/Edge Drains and factory-installed gasket.
